Velux apron damaged

[junglejim]

All of our velux aprons have damaged in the storm. One has sheared off completely (the malleable type for tiles EDW). We have some others that are flat which I thought would be better but are bent upwards and won’t reshape into position. 
 

Any ideas and best way to fix and long term solutions?

Advice from VELUX is that I need more overlap with tiles at the ends to hold it down. With these interlocking tiles (Sandtoft new rivius antique) and the wide gauge in not sure how to achieve this or whether there is any kind of workaround. Any advice greatly appreciated.

 Thank you
